Ubuntu 11.10 up to date. Banshee is used to organize and listen to my music library.
All music files are Mp3 files and are accessed using smb from my NAS.
CD covers are "included" in MP3 files (via current version of Tag&Rename tool).
The CD covers displayed in Banshee are not those included in MP3 files nor those present in directories. They are searched elsewhere from some web server.
This feature is fine with Windows 7 (WMP and VLC) and with some other upnp players.
